본 발명은 가변식 선반조립체 및 이를 갖춘 냉장고에 관한 것으로, 더욱 상세하게는 선반의 높이를 변경시킬 수 있는 가변식 선반조립체 및 이를 갖춘 냉장고에 관한 것이다.The present invention relates to a variable shelf assembly and a refrigerator having the same, and more particularly, to a variable shelf assembly and a refrigerator having the same that can change the height of a shelf.

통상적인 냉장고의 저장실 내에는 복수의 선반이 설치되어 있다. 상하방향으로 상호 이격된 선반들이 저장실 내부를 다단으로 구획함으로써 저장공간의 이용효율을 높이고 저장물을 쉽게 수납할 수 있게 한 것이다. A plurality of shelves are provided in a storage room of a conventional refrigerator. Shelves spaced apart from each other in the vertical direction to partition the interior of the storage compartment in multiple stages to increase the utilization efficiency of the storage space and to accommodate the storage easily.

이러한 냉장고의 선반 중에는 사용자가 필요에 따라 높이를 변경시킬 수 있는 것도 있다. 미국특허 5,913,584호에 개시된 가변식 선반은 냉장고 저장실 후면 쪽에 고정된 설치부재, 설치부재에 승강 가능하게 결합된 선반지지부재, 선반지지부재에 결합된 선반, 선반지지부재를 승강시키는 승강장치를 갖추고 있다.Some of the shelves of such refrigerators can be changed by the user as needed. The variable shelf disclosed in U.S. Patent No. 5,913,584 is provided with a mounting member fixed to the rear side of the refrigerator storage compartment, a shelf support member coupled to the mounting member so as to be liftable, a shelf coupled to the shelf support member, and a lifting device for lifting the shelf support member.

승강장치는 사용자의 조작에 의해 회전하는 워엄 형태의 구동기어, 구동기어에 의해 회전하는 피동기어, 피동기어에 의해 회전하는 기어축, 기어축 양단에 각 각 결합된 두 스퍼어기어, 구동기어 및 기어축을 회전 가능하게 지지하는 기어박스를 구비한다. 그리고 기어박스는 선반지지부재에 고정된다. 또 승강장치는 설치부재에 고정된 기어브래킷과, 기어축 양단에 결합된 두 스퍼어기어와 치합되도록 기어브래킷 양측에 각각 장착된 두 랙기어를 포함한다. 이러한 승강장치는 작동로드에 의해 구동기어와 연결된 회전손잡이를 사용자가 회전시키면 기어축에 결합된 두 스퍼어기어가 회전하므로 선반지지부재의 승강이 이루어진다. The elevating device is a worm-type drive gear that is rotated by a user's operation, a driven gear that is rotated by the drive gear, a gear shaft that is rotated by the driven gear, two spur gears coupled to both ends of the gear shaft, a drive gear and a gear, respectively. And a gearbox for rotatably supporting the shaft. And the gearbox is fixed to the shelf support member. In addition, the elevating device includes a gear bracket fixed to the mounting member and two rack gears respectively mounted on both sides of the gear bracket to be engaged with two spur gears coupled to both ends of the gear shaft. Such a lifting device rotates the rotary knob connected to the drive gear by the operating rod, so that the two spur gears coupled to the gear shaft rotate, thereby raising and lowering the shelf supporting member.

그러나 이러한 냉장고의 가변식 선반은 저장실 후면과 인접하는 설치부재 및 선반지지부재가 저장실 후면의 냉기유통공을 가리기 때문에 저장실의 냉기순환을 저해할 수 있었다. 특히 이러한 문제는 선반의 높이 변경을 통하여 선반지지부재의 위치를 이동시킬 경우 심화될 수 있었다.However, the variable shelf of such a refrigerator may inhibit the cold air circulation of the storage compartment because the installation member and the shelf supporting member adjacent to the rear of the storage compartment cover the cold air distribution hole at the rear of the storage compartment. In particular, this problem could be exacerbated when the position of the shelf support member is moved by changing the height of the shelf.

또 이러한 가변식 선반은 선반지지부재를 승강시키는 승강장치의 구성이 복잡하기 때문에 제조가 어렵고 제조비용이 높은 결점이 있었다. 즉 승강장치가 기어축 양단에 결합된 두 스퍼어기어, 두 스퍼어기어와 치합되는 두 랙기어, 두 랙기어를 지지하는 기어브래킷 등을 포함하는 형태이기 때문에 부품수가 많고 구조가 복잡하였다. In addition, such a variable shelf has a drawback in that it is difficult to manufacture and the manufacturing cost is high because the configuration of the elevating device for elevating the shelf supporting member is complicated. That is, since the lifting device includes two spur gears coupled to both ends of the gear shaft, two rack gears meshing with the two spur gears, and a gear bracket for supporting the two rack gears, the number of parts is complicated and the structure is complicated.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 선반의 높이를 변경하는 경우에도 냉기의 순환이 원활하도록 하는 가변식 선반조립체 및 이를 갖춘 냉장고를 제공하는 것이다.The present invention is to solve such a problem, it is an object of the present invention to provide a variable shelf assembly and a refrigerator having the same to facilitate the circulation of cold air even when changing the height of the shelf.
